Abstract: Изобретение относится к гидрометаллургии благородных металлов, а именно к способу очистки раствора родия от примесей. Способ очистки раствора родия от примесей включает выпаривание исходного хлоридного раствора родия до установления концентрации родия в растворе более 60 г/л, окисление раствора, экстракцию примесей металлов платиновой группы трибутилфосфатом и их реэкстракцию раствором соляной кислоты, отличающийся тем, что хлорид аммония добавляют в раствор родия из расчета 1,5-2,5 кг на 1 кг суммы платины, палладия и иридия (Pt+Pd+Ir) в растворе, полученный осадок отделяют от раствора, проваривают в растворе соляной кислоты с концентрацией более 180 г/л HCl и направляют на извлечение металлов платиновой группы. Технический результат заключается в расширении диапазона содержания примесей платины, палладия, иридия в растворах родия, поступающих на экстракционную очистку, что также приводит к сокращению продолжительности аффинажа металлов платиновой группы без снижения качества экстракционной очистки. 2 табл., 2 пр.

Abstract: A droplet is emitted from an orifice by generating a bubble in a small liquid chamber in response to a droplet generating instruction. By causing gradual contraction of the bubble, excessive recession of the meniscus into the liquid chamber, which would hinder subsequent droplet generation, is prevented. The bubble may be produced by a heating element. The gradual contraction of the bubble is caused by the heat dissipation of the heating element, bubble or liquid, condensation to liquid, capillary liquid supply or them, combinations of the dimension of the droplet emitted from the orifice is dependent on the parameters such as the quantity of energy applied, width of the heating element, internal die. of the liquid chamber, distance from the orifice to the heating element etc., and the physical properties of the liquid such as specific heat, thermal conductivity, thermal expansion coefficient, viscosity, etc.
